To construct a capacitor discharge tool, first gather the necessary materials. These include:

Two lengths of wire. Minimum wire requirements is 12AWG, 600 volt rating for large electrolytic capacitors used in power supplies, electric motor start circuits and camera flash circuitry

A resistor rated to dissipate the amount of thermal energy created when discharging the capacitor. Minimum requirements for resistor is 2k OHM 5w for small capacitors, 20k OHM 5w for large electrolytic capacitors used in power supplies, electric motor start start circuits and camera flash circuitry.

To discharge from small points, it may be helpful to cut the exposed ends of wire into a point shape and solder them to maintain the shape. Alternatively, the probes commonly used on multimeters can be soldered to the wires to create a more precise discharge tool.

For large electrolytic capacitors used in power supplies, electric motor start circuits, and camera flash units, you may want to solder one end to a large alligator clip and the other to a well insulated screwdriver.

This article is by far the best I've read. I have made these in the past and had to get past the amount of words used to describe what needed to be done with what. This article is straight to the point and the tips ( using alligator clip ) are excellent.

i have one query, if it is possible to discharge the capacitor in 12V 1 A power supply..? if i cut of the power, the power supply discharge the power around 6 sec but i need to discharge it with in 1 sec ..? this is possible or Not...?
